Recording apparatus

Abstract

A recording apparatus includes a liquid ejection head including a plurality of nozzles configured to eject a liquid onto a medium; and a facing portion disposed to face the liquid ejection head, wherein the liquid ejection head includes, in a plate member facing the facing portion, a head chip including the nozzles; and a protrusion member protruding from the plate member to the facing portion, the protrusion member being a rib-shaped member disposed to avoid the nozzles provided in the head chip, and the protrusion member extends in a direction intersecting the medium transport direction.

What is claimed is: 
     
         1 . A recording apparatus, comprising:
 a liquid ejection head including a plurality of nozzles configured to eject a liquid onto a medium; and   a facing portion disposed to face the liquid ejection head, wherein   the liquid ejection head includes, in a plate member facing the facing portion,   a head chip including the nozzles; and   a protrusion member protruding from the plate member to the facing portion, the protrusion member being a rib-shaped member disposed to avoid the nozzles provided in the head chip, and   the protrusion member extends in a direction intersecting the medium transport direction.   
     
     
         2 . The recording apparatus according to  claim 1 , wherein
 the head chip extends in a medium width direction that is a direction orthogonal to a medium transport direction,   a plurality of the head chips are alternately disposed at an upstream position and a downstream position along the medium width direction,   one direction in the medium width direction is set as a first direction, the other direction is set as a second direction, and the protrusion member is provided to couple an end portion in the first direction of the head chip disposed at the upstream position to an end portion in the second direction of the head chip located downstream in the medium transport direction with respect to the end portion in the first direction.   
     
     
         3 . The recording apparatus according to  claim 1 , wherein
 the protrusion member includes a corner portion at an upstream end in the medium transport direction, the corner portion being formed in a chamfered shape or an R shape.   
     
     
         4 . The recording apparatus according to  claim 3 , wherein
 the protrusion member includes a corner portion at an upstream end in the medium transport direction, the corner portion being formed in a chamfered shape or an R shape.   
     
     
         5 . The recording apparatus according to  claim 2 , comprising:
 a plurality of the protrusion members, wherein   the plurality of protrusion members include   a first protrusion member extending from a center position of the medium to a side end of the medium in the medium width direction from upstream to downstream in the medium transport direction; and   a second protrusion member extending from the side end of the medium in the medium width direction to the center position from upstream to downstream in the medium transport direction, and   the side end of the medium having a predetermined standard size in the medium width direction passes through a position deviating from the second protrusion member.   
     
     
         6 . The recording apparatus according to  claim 1 , comprising:
 a cap portion configured to cover the nozzles of the liquid ejection head, wherein   an opening portion is formed in the facing portion,   the cap portion is disposed at a position that is on the inner side of the opening portion and faces the nozzles, the liquid ejection head is movable in a direction in which the liquid ejection head is moved forward and backward with respect to the facing portion by power of a motor, and   a movement region of the liquid ejection head includes a recording position at which recording is performed on the medium, and a cap position at which a head surface of the liquid ejection head is covered by the cap portion.   
     
     
         7 . The recording apparatus according to  claim 6 , wherein
 the liquid ejection head includes an abutting portion configured to abut on the facing portion,   the facing portion is displaceable along a movement direction of the liquid ejection head and is pressed toward the liquid ejection head by a pressing member, and   the liquid ejection head is caused to abut on the facing portion by the abutting portion in a process in which the liquid ejection head moves from the recording position to the cap position, and moves the facing portion against a pressing force of the pressing member.
